Growth takes place all through the lifetime, but variably. In the case of humans, the rate of growth is faster until maturity. After attaining maturity, growth is gradual and slows down before it completely ceases.
Morphogenesis is the process where an organism is “shaped” by embryological factors such as the differentiation of cells, tissues and the development of organs and subsequent organ systems according to genetic “blueprint” of particular organism.
Types of Growth
We shall focus on the types of grwith seen in plants:
- Primary and Secondary Growth: The mitotic divisions in meristematic cells at the root and shoot apex hikes the length of the plant. This is called Primary Growth while Secondary meristem, which results in an increased diameter of the plant is known as Secondary Growth.
- Vegetative Growth: The growth in plants before flowering is known as vegetative growth and includes the formation of leaves, branches, and stems.
- Reproductive Growth: In this stage, the plants begin to flower which is a reproductive member of the plant.

Dr. Mlelwa
Dr. Mlelwa is an experienced online tutor in biology and chemistry from ordinary level to advanced level. His highest level of education is two years of doctor of medicine (MD) at Muhimbili university of Health and allied science in from Nov 2018 to Sept 2020. There after he failed to continue with Doctor of Medicine Studies due to several reasons which are out of scope of this description. He started online teaching since January 2020 in his YouTube channel (Dr.Mlelwa Lectures) by that time he was still a medical student dreaming to become one among the best tutor in medical studies, that's why he called the channel Dr. Mlelwa Lectures, comparing to Dr. Najeeb Lectures who was one of his role mode. His good performance, being the second best boy in advanced biology examinations national wise in 2018, made him one among most interesting online tutor, having influence to different students inside Tanzania as well as abroad.
